The hidden lifestyles of Bacillus cereus and relatives.
It is speculated that all members of the B. cereus group disclose symbiotic relationships with appropriate invertebrate hosts and only occasionally enter a pathogenic life cycle in which the individual species infects suitable hosts and multiplies almost unrestrained.
Detection of Enterotoxic Bacillus cereus andBacillus thuringiensis Strains by PCR Analysis
It is suggested that an approach for detection of enterotoxin-encoding genes in B. cereus and B. thuringiensis based on PCR analysis with the six primer sets for the detection of genes in the HBL and NHE operons and with the BCET1, BCET3, and BCET4 primers for the Detection of bceT.
Microorganisms as indicators of soil health
Microorganisms are an essential part of living soil and of outmost importance for soil health. As such they can be used as indicators of soil health. This report reviews the current and potential
Characterization of Emetic Bacillus weihenstephanensis, a New Cereulide-Producing Bacterium
Two psychrotolerant Bacillus weihenstephanensis strains, MC67 and MC118, that produce cereulide are reported, which are atypical with regard to pheno- and genotypic characteristics normally used for identification of emetic B. cereus strains.
Detection and characterization of the novel bacteriocin entomocin 9, and safety evaluation of its producer, Bacillus thuringiensis ssp. entomocidus HD9
Aims: To identify and characterize new bacteriocins from a collection of 41 strains belonging to 27 subspecies of Bacillus thuringiensis, and to evaluate the safety of the producers.
Hailstones: A Window into the Microbial and Chemical Inventory of a Storm Cloud
It is hypothesized that plant-associated bacteria were more likely than soil bacteria to survive the airborne state due to adaptations to life in the phyllosphere, which in many respects matches the demands encountered in the atmosphere and to grow on the suitable fraction of dissolved organic matter in clouds due to their ecological strategy.
Natural occurrence of Bacillus thuringiensis on cabbage foliage and in insects associated with cabbage crops
Characterization of the B. thuringiensis isolates from foliage showed that the majority (64% of 150 isolates) belonged to serovar kurstaki, had bipyramidal crystals and toxicity towards Pieris brassicae and/or Trichoplusia ni.
Viable methanotrophic bacteria enriched from air and rain can oxidize methane at cloud-like conditions
It is demonstrated here for the first time that viable methanotrophic bacteria are present in air and rain and knowledge on the global distribution of methanOTrophs is expanded to include the atmosphere, leading to an important possible effect of these organisms.
The members of the Bacillus cereus group are commonly present contaminants of fresh and heat-treated milk.
The data show the occurrence of potentially toxic B. cereus s.l. in both raw and heat-treated milk, thus emphasizing the requirement for precautions that prevent spore germination and vegetative proliferation by keeping the milk at low temperatures during all steps of production and dispensation to the consumers.
Long-term survival and germination of Bacillus thuringiensis var. kurstaki in a field trial.
The germination of DMU67R in rhizospheres and in the gut of nontarget invertebrates suggests that survival in the soil of B. thuringiensis is a dynamic process involving germination, cell divisions, and sporulation in specific microhabitats.
